Notes: Inspired by the legendary Moog CP3 mixer, the 713 tweaks the old-school discrete circuits into three stereo inputs and one mono channel, summing to stereo with adjustable feedback and clipping to add character.

Supplier's Notes:
ADDAC713 is the stereo version of ADDAC System's 703 Discrete Mixer.

Inspired by Moog's CP3 mixer, this is a fully discrete analogue mixer and it's not, by any means, your standard breakfast mixer, although it can behave like one.

This is a wolf in sheep's clothing. Despite its harmless looks there's a dark snarly soul behind that panel that wants to take your sounds into a realm of gritty gnarly growls.

This new version was initially thought of as a percussion mixer, with mono inputs and panning, to allow placing percussive voices in the stereo field, while keeping channel 4 in mono for low end sources like a kick drum or Bass. In the development process ADDAC System slightly changed this initial idea, adding stereo inputs for the first 3 channels, but still kept the 4th channel in mono.

All four [GAIN] controls go to extreme levels, the first 3channels also feature [PAN] controls. Feedback is used to overdrive the whole mix. As the control is turned clockwise the sound will be clipped harder until it goes completely off, this happens as feedback is increased the audio bias reference also moves up, at extreme levels it offsets the whole signal upwards until it completely goes above the top rail clipping the whole signal hence the resulting gate effect.

The [MASTER OUTPUT] sets the overall output gain of the mixer, the two leds monitor the audio output signal. The Soft clipping switch engages an anti-click circuit which adds a low pass before the output, the switch allows 3 states: Soft low pass / Off / Hard low pass.

Features:

Three channels with stereo inputs, gain and pan knob
One channel with mono input and gainknob
Feedback/gate knob
Master output volume knob
Soft clipping switch
Two Led Monitors for Left and Right channels

Notes: Five-channel mixer with mutes, built-in VCA, switchable overdrive and LED level meter. Simple, straightforward, high-quality stuff from AJH.

Supplier's Notes:
The MiniMod Muting Mixer & VCA is a 10HP wide, five channel audio mixer with many useful features. It is available with either a black (Dark Edition), or a silver front panel.

The mixer section has five input channels, and each channel includes a bi-colour tactile LED switch that can instantly mute or un-mute the channel, replicating the oscillator on/off switches on the original Model D synthesiser. This arrangement is more convenient than regular switches as each illuminated switch shows the on/off status of the associated channel and multiple buttons can be pressed at once, making it very useful for live performance.

AJH have also included a four segment LED level meter so that the overall level can be seen at a glance and adjusted to prevent the output from getting too "hot" and causing distortion in other modules further downstream.

It also features a VCA that is integrated into the output section, and this can be switched from linear to exponential response - this allows it to be used as a voltage controlled sub mixer or as a stand alone VCA with five inputs.

Lastly, AJH added a wonderfully soft and warm sounding overdrive circuit that can be switched in to add smooth, tube like distortion. This works in a similar fashion to a master volume guitar amplifier, so the amount of overdrive can be varied widely with different settings of channel and master output levels.

Notes: Aphelion packs a stereo distortion and low/high pass filter into a compact 8HP design, making it ideal for live performance setups. It features three unique stereo distortions in parallel with a continuous crossfade between them, controlled with the character knob or a cv input.

The first circuit is an overdrive that adds a lot of warmth and fattens up the sound without becoming too harsh.
The second one is a saturating wavefolder, that can add interesting extra harmonics depending on the waveform of the material.
The last distortion is inspired by the classic RAT guitar pedal. It adds an aggressive feel and grit to the sound.

A mix knob lets you blend the dry input signal with the distorted signal, before it hits the filter. Setting it fully dry bypasses the distortion effect.

If you need even more dirt, there's a handy +12dB gain switch, to really drive the inputs into overdrive. If you want to keep your low-end undistorted, you can switch on the Low-cut filter.

The non-resonant. This filter is also overdriven, adding some warm distortion and extra harmonics to the stereo filter combines a low pass and high pass stage, and uses an IC based on the classic SSM2040original signal, and limiting the output level. The cutoff knob has no effect in the centre, turning CCW creates a low pass and CW a high pass effect. It's possible to control the low and high pass filter cores independently using CV.

The filter bypass switch can be used for instant reintroduction of all frequencies into the mix upon release-a great tool for live performers.

Lastly the level knob can be used to attenuate the output.

Power: +12v - 100mA, -12v 80mA

Notes: Better known for analogue modules, it turns out Erica Synths are pretty damn good at digital too. Draw your own waveforms, build wavetables, tweak in real time and get freaky. Killer VCO.

Supplier's notes:
Erica Synths Graphic VCO allows you to draw your own waveforms, arrange them in wavetables and wavetable banks, morph between two selected waves and alter the resulting wave in advanced ways (FXes) - apply FM, phase distortion, ring modulation, wavefold/wavewrap, bitcrush.

Waves, wavetables, FXes and other settings can be saved and recalled from the memory instantly. The module has two outputs - the main output and the output with configurable suboscillator.

NB! To have the module functionality up to date, we recommend you to check the Erica Synths home pageor our social media from time to timefor announcements about firmware updates for the Graphic VCO. You can update the firmware of the module via miniUSB cable. More detailed instructions of the firmware update can be found in the User Manual.

The sound is clean, modern, punchy and detailed thanks to the unit running at 96kHz - quite different to some low bit-rate wavetable oscillators on the market. Wavetable interpolation is smooth as butter and with the built-in effects you can dirty things up in many different ways. The module scores highly on the sound front. The Graphic VCO is a very capable oscillator module with excellent sound quality and a lot of features that could make it the right choice, especially if live performance is your thing. - Sound On Sound
The bottom line is that the Graphic VCO is a joy to use. It's a module that's unashamedly digital, yet unmistakably eurorack. I think Erica showed a great deal of careful judgement and restraint in the design of this module. It would have been easy to have made it bloated and cumbersome trying to cram as many features as possible into it, but they kept it fairly simple which keeps the module fun and immediate in use. It's capable of a huge tonal palette ranging from beautiful to brutal that is bound to fit in with a lot of different styles and systems. - Ask Audio
The ability to draw and then effortlessly jump between different custom digital waveforms in this way feels unique on the Eurorack stage, and allows for a wide range of tones and transitions between them. - Orb Mag

20hp, 42mm deep.

Notes: LYRA8-FX is a processor that can give you a significant part of the mysterious LYRA-8 sound thanks to the FX section from the LYRA-8, expanded with CV controls and packed into a Eurorack module.

It contains a double modulated lo-fi delay with cross-feedback and the unique possibility of self-modulation, where the delay output signal modulates its own sample rate. Also, it packs a parallel distortion with CV control of the drive. The distortion is after the delay. It's much more than a delay - you can get a simple reverb, comb filter, chorus and much more cool FXs which are hard to describe.

It has a famous LYRA-8 build quality - no SMD, no twisted plastic shafts.

Notes: TouellSkouarn Strakal Brulu is a handmade distortion and fuzz module. The great sound is due to the new-old-stock east-German germanium transistors.

Very characteristic for the module's sound if the feedback that is coupled to the feedback. The more fuzz, the more feedback - the Strakal Brulu 2 can get pretty nasty and it screams a lot at high fuzz settings and low input level. The fuzz amount can be voltage controlled, with an inverse attenuator. Input and output levels can also be set separately.

Notes: C4RBN is a 4/2-pole state variable filter with input saturation, output wavefolding and more. It offers a wide range of characters, from nice and clean filter sounds to screaming, squeaky, sounds.

An innovative input saturation circuit and the output wavefolder of WMD's classic SYNCHRODYNE filter bring great sonic flexibility.

Features:

3 independent 2 pole outputs for High Pass, Low Pass, and Bandpass
Inverting Attenuator (attenuverter) for FM allows for positive and negative CV control over the cutoff frequency

Notes: Part of Xaoc's Leibniz Binary Subsystem, the updated Drezno ADC/DAC module builds on the original with higher resolution converters, allowing you to use it for pitch quantisation.

Supplier's Notes:
Drezno II is an improved version of the original Drezno module. It is an essential member of the 8-bit Xaoc Devices Leibniz Binary Subsystem. The Leibniz subsystem is a family of modules that operate on 8 binary (two-state, on/off) signals. These signals are arranged as 8 bits of digital data and may represent analogue signals and voltages, or they may be whatever you want them to be (clocks, gates, rhythms, etc.).

Drezno features an ADC (analogue-to-digital-converter) and DAC (digital-to-analogue-converter), allowing it to act as an analog front-end of the system. In other words, Drezno allows one to convert analogue signals and CVs into digital numbers, as well as to obtain analogue signals back from some other digital numbers (or 8 binary signals). Between these two conversions there is a whole universe of digital shenanigans waiting to happen resulting in all kinds of signal transformations and modulations.

Both (ADC and DAC) sections of Drezno can work independently, or they can be linked. Input and output range of analogue signals may be adjusted using Gain and Offset sliders. Individual bit outputs (for the ADC) and inputs (DAC) allow for extensive cross-patching and the creation of complex waveforms and rhythms. A very fast clock (up to 2MHz) at which the conversions are performed may be replaced with any external clock (for each section separately).

Compared to its predecessor, Drezno II uses new converters of much higher resolution which results in much lower noise floor and higher accuracy. The lower bits are much more stable than before. It is easy now to use Drezno for quantizing pitch voltages with accurate results with 128 or 256 semitone steps. Potentiometer ranges are factory calibrated for precise chromatic scale. A new switch on the front panel allows the user to select the calibrated range of 10Vpp or 20Vpp, so that the lowest bit or the second bit correspond to 1 semitone.
